Read this to your crew
Today's talk is about where you stand. The line of fire is the path something will take if it moves, falls, swings, springs loose or rolls. When your body is in that path, you are betting that the load, the line or the machine does exactly what you expect.
Look for five things. Moving equipment: the path of a truck, a loader or a forklift, and its blind spots. Swinging loads and rotating cranes: the load, the tag line and the counterweight as the upper works turn. Falling objects: anything overhead, from a scaffold plank to a dropped tool. Stored energy: a spring, a chain or strap under tension, a pressurized line. Rolling or shifting material: pipe, rebar bundles, a pallet on a slope.
Here is the habit. Before you start a task, ask: if this lets go, where does it go? Then put yourself somewhere else. Stand to the side of a strap you are tightening. Stay out of the swing area of a crane or an excavator. Never walk under a suspended load. Never stand between a backing vehicle and something it could pin you against.
The rules mark some of these lines for us. Around a crane, control lines, warning lines, railings or similar barriers mark the swing hazard area, or warning signs and high-visibility markings where barriers are not feasible (29 CFR 1926.1424(a)(2)(ii)). On a machine, guards protect us from the point of operation, nip points and rotating parts (29 CFR 1910.212(a)(1)). Those barriers are there because people got hurt where they stood, so do not step over them.
The hardest line of fire to see is the one we create ourselves: pulling a wrench toward the face, cutting toward the body, kneeling in front of a line under pressure, putting a hand on top of a load as it lands. Slow down long enough to see it.
If you see someone in the line of fire, say so, out loud and right away. Nobody here will be offended that you told them to move.
Three questions for the crew
- On today's job, what could move, fall, swing, release or roll, and where would it go?
Listen for: Specific loads, vehicles, straps, hoses and overhead work. Each answer comes with a place to stand that is out of the path. - Where on this site do barricades or warning lines mark a hazard area, and who goes inside?
Listen for: Crane swing areas, overhead work zones, pressure tests. Only the people the work needs, and only when the operator knows they are there. - What do you say when a coworker steps into the line of fire?
Listen for: A short, clear warning, right away. Everyone is expected to speak up.
Which OSHA rules cover the line of fire?
No single OSHA standard is called line of fire. Several rules mark the path of a moving hazard and keep people out of it.
Cranes: each employee assigned to work on or near the equipment is trained to recognize the struck-by and pinch/crush hazard areas of the rotating superstructure (29 CFR 1926.1424(a)(2)(i)), and control lines, warning lines, railings or similar barriers mark the boundaries of those areas, or, where the employer can show barriers are not feasible, warning signs and high-visibility markings on the equipment (29 CFR 1926.1424(a)(2)(ii)). Before an employee goes to a spot in the hazard area that is out of the operator's view, the operator is informed (29 CFR 1926.1424(a)(3)(i)).
Machines, in general industry: one or more methods of guarding protect the operator and other employees in the machine area from hazards such as the point of operation, ingoing nip points, rotating parts, flying chips and sparks (29 CFR 1910.212(a)(1)).
Vehicles: in construction, a motor vehicle operating within an off-highway jobsite not open to public traffic (29 CFR 1926.601(a)) with an obstructed view to the rear is used only with a reverse signal alarm audible above the surrounding noise, or backed up only when an observer signals that it is safe (29 CFR 1926.601(b)(4)); earthmoving and compacting equipment has the same choice of an alarm or a signaler (29 CFR 1926.602(a)(9)(ii)).
The paragraphs, word for word:
“(i) Train each employee assigned to work on or near the equipment (“authorized personnel”) in how to recognize struck-by and pinch/crush hazard areas posed by the rotating superstructure.”
“(ii) Erect and maintain control lines, warning lines, railings or similar barriers to mark the boundaries of the hazard areas. Exception: When the employer can demonstrate that it is neither feasible to erect such barriers on the ground nor on the equipment, the hazard areas must be clearly marked by a combination of warning signs (such as “Danger—Swing/Crush Zone”) and high visibility markings on the equipment that identify the hazard areas. In addition, the employer must train each employee to understand what these markings signify.”
“(a) Machine guarding—(1) Types of guarding. One or more methods of machine guarding shall be provided to protect the operator and other employees in the machine area from hazards such as those created by point of operation, ingoing nip points, rotating parts, flying chips and sparks. Examples of guarding methods are—barrier guards, two-hand tripping devices, electronic safety devices, etc.”
“(4) No employer shall use any motor vehicle equipment having an obstructed view to the rear unless: (i) The vehicle has a reverse signal alarm audible above the surrounding noise level or: (ii) The vehicle is backed up only when an observer signals that it is safe to do so.”
How often did OSHA cite these rules in FY2025?
| Standard | Construction sites | Other industries | All FY2025 citations |
|---|---|---|---|
| 29 CFR 1926.1424Crane work area control | 9 | 0 | 9 |
| 29 CFR 1910.212Machine guarding, general requirements | 111 | 2,555 | 2,666 |
| 29 CFR 1926.601Motor vehicles, construction | 36 | 5 | 41 |
| 29 CFR 1926.602Material handling equipment, construction | 237 | 14 | 251 |
Citation items under 29 CFR issued Oct 1, 2024 to Sep 30, 2025, at federal and State Plan inspections, counted by HazComFast on U.S. Department of Labor enforcement data (extracted Oct 13, 2026). Construction means an inspection whose NAICS code starts with 23. The counts describe inspected establishments, not every employer.
Where is the line of fire on a jobsite?
| Source | The path | Where to stand |
|---|---|---|
| Backing truck or loader | Behind the vehicle and in its blind spots | In the driver's view, out of the travel path |
| Crane swing | The swing area of the counterweight and the load | Outside the barricade |
| Suspended load | Below it and wherever it can swing | Clear of the load, guiding it with a tag line |
| Strap, chain or cable under tension | The direction it snaps back | To the side, never in line with it |
| Pressurized hose or line | The whip path if a fitting lets go | Clear of the line during testing, with whip checks on hose connections |
| Pipe, rebar or a pallet on a slope | Downhill | Uphill or to the side, with the load chocked |
